Rusan Screw allen M4x30

• M4x30 Allen screw format: the M4 thread and 30 mm length suit mounting jobs that need a slim, precise fastener, helping keep scope-mount components securely aligned.
• Made for mount-related use: this Rusan accessory is intended for mounts, making it a practical replacement or spare part for maintaining a secure optic installation.

About the Rusan Accessories Series

Rusan Accessories covers the supporting parts that keep the company’s mounting and adapter systems working as intended. The series sits alongside Rusan-Mikron’s scope mounts, rings, and rails, and it is especially relevant to users who rely on modular setups, clip-on interfaces, and repeatable optic mounting. Within the wider Rusan range, these accessories support both conventional and modular adapter systems, reflecting the brand’s emphasis on practical compatibility across different rifles and optical devices.

The series is shaped by Rusan’s long focus on mounting solutions for sporting and hunting optics. It includes small but important components such as screws, spare parts, and adapter-related accessories that help maintain fit, alignment, and day-to-day usability. That matters in the field because a mounting system depends not only on the main clamp or rail, but also on the quality and correct sizing of the hardware that holds everything together. In that sense, Rusan Accessories is less about adding features and more about preserving the reliability, serviceability, and clean mechanical function that users expect from a well-made mounting setup.

About the Rusan Screw allen M4x30

The Rusan Screw allen M4x30 is a straightforward mounting accessory designed for situations where the correct fastener matters as much as the larger mount itself. As an M4x30 Allen screw, it is suited to mount-related applications that require a slim threaded fastener with enough length to secure components properly while still allowing controlled installation with a hex key. In practical use, that means more consistent tightening, less risk of using an ill-fitting substitute, and a cleaner match with precision mounting hardware.

For scope-mount maintenance and assembly, small parts like this play an important role in keeping the system dependable. A dedicated screw helps preserve the intended fit of the mount, which in turn supports stable optic positioning and reduces the chance of movement caused by mismatched hardware. The black finish also keeps the screw visually discreet on modern mounts and accessories, which is useful when replacing a visible external fastener. Whether it is used as a replacement part, a workshop spare, or part of a fresh installation, this Rusan mounting screw is best understood as a practical service component: simple in form, but important for maintaining the secure mechanical connection that optic mounts depend on.

About Rusan

Rusan-Mikron is a Croatian manufacturer based in Marija Bistrica, with roots in the Rusan family’s metalworking business dating back to 1983. Željko Rusan opened a gunsmith shop in 1986, and the company began producing scope mounts in 1993. That background explains why Rusan is closely associated with precision-made mounting hardware rather than general shooting accessories.

Today, the company manufactures scope mounts, scope rings, Picatinny rails, and firearm tuning products, along with adapter systems for night-vision and thermal-imaging devices. Rusan is particularly well known for its clip-on sight adapter solutions, including the adapter clamp it introduced in 2009. Across its product range, the company focuses on practical machining, repeatable fit, and compatibility with a wide variety of rifles and optics, which makes its products familiar to hunters and other users who need dependable mounting components.
